The average monthly salary of 30 employees and 5 managers is Rs. 80000. One manager with salary Rs. 180000 is replaced by a new manager. If the average monthly salary now becomes Rs. 78500, then what is the monthly salary of the new manager? Correct Answer Rs. 127500
GIVEN:
Average monthly salary of 30 employees and 5 managers = Rs 80000
CALCULATION:
Total salary of 30 employees and 5 managers = 35 × 80000 = 2800000
Let the salary of new manager be = x
⇒ (2800000 – 180000 + x)/35 = 78500
⇒ x = 2747500 – 2620000 = Rs. 127500
∴ Salary of new manager = Rs. 127500
Shortcut Trick
Let the salary of new manager be = Rs. x
⇒ (180000 – x) = (80000 – 78500) × 35
⇒ x = Rs. 127500
